This invention relates to improvements in air compressor mountings fortractors.

The primary object of the invention is to supjply a'unit mounting totractors for supporting an air compressor without altering the tractorin any form.

A further object of the invention is to mount the unit mounting in linewith the magneto mounting, shifting the magneto beyond the compressorwhich is at present located adjacent the timing gear case of the motor,the compressor receiving its drivefrom said timing gears.

Another object of the invention is to provide a mount for supportingthe'magneto in line with the compressor, said magneto being driven bythe crank shaft of the compressor.

A still further object of the invention is to provide a pressure oilfeed connection through the mount from the force feed oiling system tothe compressor.

By the use of my new and improved compressor and magneto unit mount, thecompressor and the magneto are driven directly from the timing gearswithout altering the gears in the motor.

In the mounting of my new and improved unit, there are no extraholes todrill and tap, nor any part of the engine to be altered, the presentmagneto mount is removed from the timing gear housingand my mount isreplaced in the same location.

These and other incidental objects will be apparent in the drawings,specification and claims.

Referring to the drawings:

This invention is particularly adapted to tractor engines of the typewherein the magneto is supported by a bracket mounted to the timing gearcasing and the magneto is operated by a gear of the timing gear train.This type of engine construction is employed in the Internationaltractors which are manufactured by the InternationalI-Iarvester Company.Accordingly, in View of the Wide popularity of the Internationaltractors, I-have shown my invention incorporated'in an Internationaltractor engine. It will be 'apparent, however, that the invention isequally applicable to any engine of this type. 7

Referring now to the drawings, the usual prior art construction is shownin Fig. 1 as comprising an engine I, having the usual timing gearhousing 2, which is supported by the timing gear supporting plate 3fixed to the front end of the engine cylinder block. The prior artmagneto mount is indicated at 4 in Figure 1 and is bolted by means of aflange 4' to the timing gear plate 3. A magneto drive shaft 5 isjournalled within suitable bearings located within the housing 6, theopposite end of the shaft having a gear l9 keyed thereto and driven byan idler gear 20 from the timing gear 2 I The idler gear 20 is mountedon a, shaft 22 that is supported by the mount flange l.

M new and improved compressor and magneto mount, as shown in Fig. 2,consists of a main body or frame I, and a bracket 8 removably attachedthereto. The mount 1 consists of a flange 9 formed on one end of thetubular body portion ill and a flange II formed on the opposite end ofthis tubular portion. The flange 9 is substantially identical to theflange 4' of the prior'art mount and, in like manner, is adapted to bebolted to the timing gear plate 3. The bottom of the flange l l extendsdownwardly to form an arm [2 which is reinforced by a web or gusset [5.The arm I2 is adapted to support the magneto bracket 8, which has aflange l3 for engaging the face of the supporting arm l2 and beingsecured thereto by the bolts I 4.

As shown in Fig. 3 the compressor I6 is bolted to the flange l l by thebolts I1 and has a shaft l8 which, as also shown in Fig. 6, extendsthrough the tubular body ll] of the compressor mount 1.

.After the compressor and the mount are bolted to the timing gear frame3 the gear l9 (Figs. 3 and 6) is keyed to the compressor shaft l8 in thesame manner that it was mounted on the prior artmagneto shafts. Thisgear I9 is driven by 3 timing gear 2| as in the prior art arrangement.All of the gears I9, 20 and 2| are identical to those used in thedriving of the magneto on the prior art mounting illustrated in Figure1.

The idler gear 20 is mounted to my magneto mount 1 by a stub shaft 22 inthe same location that it is mounted to the shaft 22 of the prior artmount 4. The shaft 22 is locked within the hub 23 by a suitable washer24 and locking nut.

25. An oil passage 26 is cored into the flange 9 of the mounting I,extending to the bearing of the hub 23 and having a laterally extendingport 26' opening through the face of the flange 9. The port 26' ispositioned to communicate with the pressure feed port 21 located withinthe timing gear plate 3. The oi-l delivered from the; motor underpressure is forced through the feed-port: 2'! to the port 26" and intothe passage 26, and to bearing 23, from which it isdelivered throughthepiping 28 to the compressor 16.- at 291 and is forced through thecompressor hearings in. the present well known manner.

The delivering of the oil pressure from the mo tor through my mount intothe compressor is one of the features of my invention. The magneto mount8 supports the magneto 30 which was formerly supported by the mount 4'that was re.- moved from the engine. The magneto is coupled to the shaft[8 of. the compressor H5 at 31, in the usual manner, and is driven.

In the installation of the-compressor, the mag,- neto mount 4 that comeson they engine is; simply removed and my unit 1 is bolted on in theexact. position having been occupiedby the mount 4'.

When the compressor is. installed it may have a gear 19 keyed thereon.The gear 20 may also be. supplied with my new and improved unit. mountso that these gears will fit right in where the old mounting assemblyhad been removed, including its gears. The magneto is then bolted inplace upon the mount 8 at. 32 and hooked up; to. the compressor as abovedescribed.

It will be noted in Figures 3 and 4 that thecompressor is set at anangle to the vertical line of the motor. The object of setting thecompressor at anangle is to avoid interference with the generator 33.

I do not wish to be limited to the exact mechanical structure as shownand described, as other equivalents may be substituted still comingwithin the scope of. my claims.
